v METAL WEATHER SIRI? v Filed Feb. 4. 1929 wam Patented July 5., 1932YV WILLIAM J'. DENNIS, OIE CHICAGO, ILLINOIS METAL WEATHER STRIP Application led February 4,51929'.` lSerial No.V 337,404.

My invention has to do with metal weather stripping and may be considered an improvement of the invention described and claimed in my copending application Serial N0. 156,865 filed December 24, 1926.

My invention relates to weather strips for use on doors, Windows, or the like, for pre* venting the ow of cold air, dust, dirt, or

,.3 the like, through or past the windows or doors.

The invention has among its objects the production of a Weather stripping that is of simplified construction, compact, convenient,

p durable, reliable, efficient and satisfactory for use wherever found applicable.

A particular object of the invention is to provide an improved weather strip which may be quickly and easily installed.

Still another particular object of the 1nvention is to provide an improved method of producing weather stripping, which method will enable it to be quickly and easily adjusted to meet various conditions.

Still another object is :to provide such a weather strip which will have means adjacent the marginal portions thereof to prevent buckling of the strip, said means also serving, if desired, as a guide for a knife A Y- or other suitable instrument for forming a crease in the strip along which the strip may bend longitudinally.

Many other objects and advantages of the construction herein shown and described i will be obvious to those skilled in the art Fig. 4 is a fragmentary sectional view taken through a window on which a weather strip embodying my invention has been in Y stalled.

' Referring first, to Figs. 1 to 3, inclusive,

thereference character 10 designates a door hingedlymounted in adoor frame 11. Betweenthe free edge of the door 10V andthe adjacent .portionof the door-frameY 11is i' shown a weather strip 14 embodying my-in- 5 vention, the weather strip being secured to the vframe 11 by screws or` nails 15 orother suitable means. ,y i .As `best shown in Fig., 3, my improved i" weatherstrip A14 isv preferably formed from 60 a .strip .of sheet metal having some resilience and itpreferably comprises a marginalportion 17 adapted tobe secured to the frame 11 or to any'other suitable support by the nails or screws 15. Formed integrally with the ab marginal portion 17 is a substantially 'flat leaf portion19." Formed on the strip 'b'etween Ithe leafy portion 19 and the marginal portionl? isal pair of parallel ridges or fi grooves 21 depending on the side from 70 which Ethe view is taken.l `Asshown in Fig. 3,; the elements represented at 21appearas a pair of parallel ridgeswhile obviously von the opposite side of thestrip grooves will be f. seen separatedL by a ridgel22.v On the oppositeside of the leaf 19 is a similar Apair of grooves `or ridges 21. p

,'Adjacentthe' ridges 21 is a substantially Hat portion 24 whichles in substantially the same plane asthe leaf portion 19. Adjacent the flat portion 24 and preferably inte ral therewith, isan arcuate longitudinal bea 25, the-free edge of which is folded back as at26 so-as to form a reinforcing ridge conforming with Vthe arcuate conformation of the bead 25.v Similarly, the free edge of the marginal portion 17 is folded back to form av reinforc# ing'sftrip 28. Y Y. y

`When it is desired to install the strip de- "1 scribed above, it is placed incontact withY a door frame as shown in Fig. 2, and tacks, screws, or' similar attaching members are passedthrough the apertures 23 and vserve tov secure the strip to the frame. An instru-f ment having arelatively sharp edge, is then drawn with some force along the groove 22 betweenthejparallel ridges 21. Such an in-i strument may comprise a screw driver, a4 knife",an awla` diskfhaving arelatively sharp i edgeand rotatably mounted in a' suitable u com handle, or any other convenient tool. The result of this act is to cause th-e free portion of the strip beyond the groove 22 to spring outwardly from the frame and to take a position substantially as shown in Fig. 2, so that the arcuate bead 25 may be in relatively close Contact with the door 10 when the latter is closed. The parallel ridges may therefore be said to have two functions: First, it serves as a guide for the knife or other tool which is drawn along the groove 22 and prevents slipping of the knife, with resultant marring of the strip. Secondly, the ridges may Abe said to have a stitfening eiect on the strip and therefore tend to increase its efficiency after it has been applied. As a result of this function the marginal portion 17 will lie perfectly Hat against the door frame and there will be a total absence of bulging between the securing members,r hence, it will be practically impossible for air, dust, etc. to pass between the strip and the door frame.

The parallel ridges 21 perform a similar function to the last one indicated for the ridges 21 that is, they tend to stiii'en the free edge of the strip and prevent undulations therein, causing the strip to make a firm contactk all along its free edge with the door.

In Fig. 4 is shown an improved weather strip embodying my invention as applied to a window. Thus, the reference character 30 designates generally a window trame in which a window'sash 31 is slidably mounted. Theimproved weather strip-17 is secured to the frame 30 by means of nails or screws 15, or other suitable means, andV has its arcuate bead 25 in contact with the sliding edge of the sash 31. Of course, the weather strip 14 may extend the full length of the window so that its bead 25 will engage the sash 31 at all times. It will be readily understood that the weather strip 17 may be quickly and easily adjusted at any time to bring its bead 25A into more effective engagement with the sash 31. This may be accomplished as described above by drawing a sharp tool or instrument between the ridges 21.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described or uses mentioned.

What I claim as new and desired to secure by Letters Patent is:

A weather strip comprising a thin-metal plate having a plurality of longitudinally eX- tending spaced apart grooves, an inwardly turned flange on one edge portion of the plate providing rigidity adapting said edge portion for a nailing strip, the other longitudinal edge portion of theplate comprising, an arcuate bead having an inturned flange,

In witness whereof, I hereunto subscribe my name this 30th day of January A. D.,
